Title: Apparatus for direct shear stress testing of sample

Abstract: An apparatus for direct shear stress testing of a sample includes a base plate, a supporting member, a fixing member, and a sliding member. The supporting member includes a supporting plate. The fixing member includes a stationary shear plate having a first receiving hole. The sliding member includes a movable shear plate interposed between and in sliding contact with the supporting plate and the stationary shear plate. The movable shear plate has a second receiving hole. The movable shear plate is slidable relative to the stationary shear plate to align the first and second receiving holes so as to receive the sample therein, and to misalign the first and second receiving holes so as to cause the sample to yield. The direct shear stress of the sample can thus be tested accordingly.
